Abstract

The invention relates to a solid state disk and a solid state disk data protection method, device and equipment. The solid state disk comprises a main control chip and a plurality of flash memories. The main control chip is electrically connected with the flash memories, so that the solid state disk provides a storage space through the flash memories; wherein the plurality of flash memories are divided into different storage areas, and each storage area is correspondingly configured with a corresponding protection level; different protection levels correspond to different data storage modes. The physical space of the solid state disk is divided into a plurality of storage areas, and different storage areas are used for storing different data, so that when the data stored in the solid state disk is protected, the different data can be correspondingly stored in the corresponding storage areas, and the different storage areas are configured with corresponding protection levels, so that the protection level of the data stored in the solid state disk is improved. In this way, different data can have corresponding protection levels when written into different storage areas, and therefore the purpose that different data are subjected to safety protection through different protection modes is achieved.

Description

technical field [0001] The present application relates to the technical field of hard disk data management, and in particular to a solid state hard disk and a method, device and equipment for protecting solid state hard disk data. Background technique [0002] With the large-scale application of SSD (Solid State Drive, hereinafter collectively referred to as SSD) in enterprise servers, industrial computers, automotive electronics and personal computers, data security is also increasingly valued. Since SSD is composed of control circuit and software running inside (hereinafter referred to as firmware), with the improvement of NAND process, the complexity of SSD internal firmware also increases, so hacker attacks and human factors damage data security. It has caused a deadly threat, so how to better protect the data stored in the SSD and prevent data from being tampered has become a new challenge for SSD manufacturers. In related technologies, the data protection modes adopte...
